看完本文让你对该库有个80%的了解,足够写一般的小软件.
本文的案例,讲解都是我从PySimpleGUI看过后整理的,下面是官网网址https://pysimplegui.readthedocs.io/en/latest/cookbook/

def 总体说明():
#下面这个layout变量就是控件的集合,里面放空间
#将来我们直接把这个变量传到窗口(屏幕)那里
#你可以把它当作实际内容
#以下是个简单的例子
layout = [[sg.Text("要显示在窗口上的文字")], [sg.Button("完成")]]
#他还有参数,你懂的:title='Options',etitle_color='rd',
#sg.Window(),创建一个窗口,第一个参数是窗口名称,有latout参数就是本窗口的内容
window1 = sg.Window("Jarvis",layout=layout)
#可以设置no_titlebar=True就没有边框了,而且不会显示图标(暂时不清楚是怎么回事)
#还有个类似的:form = sg.FlexForm('Everything bagel', default_element_size=(40, 1))
#上面那种方式是在构造的时候就传入内容,我们也可以在后面调用window对象 的Layout()方法,参数就是你要传入的内容
window1.Layout(layout)
# Read()是阻塞式方法,会阻塞程序的进行,直到Button被点击才有返回值
button, value = window1.Read()
#返回一个元组,
#元组的第一个元素就是按钮的名称(字符串类型,你在layout那里填的)
print('button:', button)
#第二个元素是字典,返回字典,所有可输入,可选择的值.键是由零开始的索引,值就看你设置的value了
print('value:', value)
